The four ways to get online

Only fields we can verify are compared. Roaming pricing belongs to your home carrier — we quote no numbers we can’t check. Public Wi-Fi is a backup connection, not a full setup.

By scenario

017-day tourist → travel eSIM only

Maps, translation, messaging. Home SIM stays on for incoming SMS.

02Alipay / WeChat heavy → dual SIM

eSIM for foreign apps + local SIM for +86 verification codes.

03Business with laptop → eSIM, verify hotspot

Tethering is per-plan; unlimited plans often cap it.

04Locked / older phone → local physical SIM

Airport counter or carrier store, passport in hand.

Set up

Make it work

  1. Confirm support

    Settings → Cellular shows “Add eSIM”, and the phone is carrier-unlocked.

  2. Buy on home Wi-Fi

    Save the QR code and order number offline — not only in a cloud app.

  3. Install before boarding

    Provider sites and apps can be unreachable from mainland China. Complete any required activation step before you fly; you can keep the eSIM’s data line off until landing.

  4. Land & switch on

    Turn on the eSIM data line and its data roaming; turn your home SIM’s roaming off.

  5. No signal? Pick the network manually

    Settings → Network Selection → choose China Mobile, China Unicom, or China Telecom.

Don’t buy on a “no-VPN” promise alone. Routing can change — keep a backup (a VPN installed at home, or a second eSIM), and save the provider’s support email offline: from inside China, email is the channel that reliably works.
If it fails after landing — the four fixes
  • No signal: turn data roaming on for the eSIM, then manually try China Mobile, China Unicom, or China Telecom.
  • Apps still blocked: switch to the backup you installed at home — a VPN set up before departure or a second eSIM. Don’t debug on the street; compare eSIM vs VPN for China.
  • Hotspot missing: tethering is allowed per plan, not per provider; unlimited plans cap it most often.
  • Activation stuck: use hotel or airport Wi-Fi and email support with your order number and a screenshot — provider apps often can’t load exactly when you need them.

FAQ

The hard questions

Most short trips on an unlocked eSIM phone: a travel eSIM installed before you fly. You need a local physical SIM only if you must have a +86 number (Alipay / WeChat SMS). Roaming is the home-carrier option — often the most expensive per GB. Dual SIM is for people who need both foreign-app data and mainland SMS.

Use hotel or airport Wi-Fi and email the provider’s support with your order number — apps and websites may not load from inside mainland China, but email usually does. If you have no eSIM yet, the realistic route is a local physical SIM: airport counter or carrier store, passport in hand.

Only a local physical SIM. Travel data eSIMs are data-only — they cannot receive the mainland SMS verification codes that Alipay or WeChat sign-up sends.

Yes — most modern phones support dual SIM. The standard setup for travelers who need both: an overseas eSIM for foreign-app data plus a local physical SIM for the +86 number.

Product-dependent — some carrier plans must be pre-activated outside mainland China before first use. Consumer travel eSIMs should always be installed before departure, since the provider’s site or app may be unreachable from inside China.
